It occurs in episode three of the season, titled "Breaker of Chains," in which Daario Naharis offers to fight on behalf of Daenerys Targaryen against the rider from Meereen. You may more clearly recall this moment as the "battle of public urination" or "that time Daario killed a guy via his horse."

Moments before the epic duel, we witness the champion of Meereen taunting the Mother of Dragons in "Low Valyrian." No subtitles are offered for the audience and Dany's in-show translator Missandei keeps tight-lipped on the subject matter.

Turns out, Peterson confessed, the soon-to-be-killed Meereen warrior was hurling some classic French guy Monty Python and the Holy Grail-style insults at Dany.

"That was [show creator] Dan Weiss’s idea, and it was so hilarious that I had to do it," Peterson said.

And it seems Monty Python may have some excellent advise for our Khaleesi/Mother of Dragons/Breaker of Chains/Queen of Meeren/First of Her Name/Queen of the Andals and the First Men. "You can't expect to wield supreme executive power just because some watery tart threw a sword at you," a character says in another scene. That goes for dragons, too.
